In the second aliyah of Parshas Re'eh, we are instructed about bringing korbanos (offerings) in the Beis Hamikdash. We are also given permission to eat non-korbanos meat outside of the Beis Hamikdash. This falls into the category of reshus, things that are neither forbidden nor obligatory, but rather permissible. It is important for us to be able to distinguish between kodesh (holy) and chol (mundane), as we work to elevate the mundane to the level of kodesh with the proper attitude and mindset.
